Metrolinx has cut down 167 large trees along the Georgetown South corridor, and, though they are replacing them 3:1, residents south of here are upset, according to BlogTO.
I know, because I got a C+ in one forestry course, that the devil is in the details for things like this; replacing trees can be like comparing apple (trees) and orange (trees). Replacing large mixed hardwoods with three times the number of small pines is hardly reforesting.
Moreover, the trees will not be planted along the tracks:
planting of the replacement trees [will be] away from the rail corridor, though the location couldn’t be confirmed at publication time. The trees can’t be returned too close to the new tracks because safety rules require train drivers to have a clear view at all times.
